Product is perfect but on a Kawasaki you do need to remove the cotter pin from the axle bolt to allow the spindle to pass through the axle. Difficult to know whether this is a safe idea or not and whether the bobbins themselves provide sufficient additional security to stop the bolt ever loosening. Some advice on this would be useful in the instructions.
